The Toolkit for Conceptual Modeling (TCM) is a collection of graphical editors
for different software specification methods. It contains generic editors (for
generic diagrams, tables and trees), editors for Structured Analysis
(entity-relationship diagrams, data and event flow diagrams, state-transition
diagrams, function refinement trees etc.) and editors for UML (static-structure
diagrams, use-case diagrams, activity diagrams etc.). TCM supports various
levels of constraint checking for single documents. Features to be added later
include constraint checking across documents and executable models, and support
for hierarchic graphs. In addition to the TCM file format, TCM outputs Plain
PostScript, Encapsulated PostScript, PNG and the XFig file format. The TCM file
format is simple to read and parse so other forms of output can be generated
easily.
